Here’s an interesting quote by Ernest Holmes:

“What is a habit? A habit is the form that desire takes; it is a desire for something that will give satisfaction. At the root of all habit is one basic thing, the desire to express life. There is an urge to express in all people, and this urge, operating through the channels of Creative Mind, looses energy into action and compels the individual to do something.

Back of all desire is the impulse of Spirit to express. In man, this impulse must express at the level of his consciousness.

Some express constructively and some destructively.

Suppose a man who has the liquor habit comes to you to be healed. You would not pray that he be healed, for you would know that you are dealing with a man who has the desire to express life and who thinks that he must express it in terms of intoxication. He once thought this expressed reality to him; he now knows that it does not, but he has not the will power to stop; for the habit has appeared to take complete possession of him. (It is well to remember that unless we control thought, it will control us.)

In giving the treatment, first recognize who and what he is, saying something like this: “He is the full and complete expression of the Truth, and, as such, he is free from any sense of limitation. He is free from any delusion or fear of delusion. He knows that the Spirit of Truth within him is complete and always satisfied. That thing which calls itself the liquor habit has no power over him and cannot operate through him. By the power of this word, it is now completely destroyed and forever obliterated.” Then see him free and satisfied. Wait until you, yourself, are sure of the statements made, realizing that the work is done. This is the treatment.”
